Change the look of bars, wedges and more in Keynote on iPad
A data series is a set of related values in a chart — for example, all the bars of the same colour in a bar chart, or a single line in a line chart.
You can emphasise trends in your chart by changing the appearance, position or spacing of one or more of the data series.
Change colours and shadows in chart elements
You can change the look of any data series in a chart to differentiate it from other series. For bar charts, for example, you can fill the bars in each series with a different colour or a colour gradient, apply a different outline (stroke) style and more. For scatter charts, you can change the symbol that represents each point and add connection lines between the points.
Note: You can’t change the look of a single data point in a series (a single bar in a bar chart, for example). All changes you make apply to every data point in the series.
Tap the chart, then tap Edit Series.
Tap the series you want to edit, then use the controls in the menu to make changes.
The changes affect only the selected data series. To change another series, tap All Series, tap the series you want to edit, then make changes.
To edit multiple series, tap Select, tap two or more series, then tap Format Selected Series.
Tip: You can choose a coordinated set of colours for all the data series in the chart at once. Tap the chart, tap 
, then tap a style in the Chart tab.
